It doesn't get much better than the zambons. They are good shit. Personally I wouldn't bother injecting them though... unless you're already shooting ED. I'd go ahead and shoot em on injection day... but if you're not shooting anything else, just drink the stuff. You won't see much difference either way.
I have them, and I love them. 100mg EOD along with Tren and Prop does me right. I will be cracking the amps in the not too distant future. Right now using Primo and Prop.
